Windscreen wiper motor wiring

[frenchy]

Hi guys,
I have a Peugeot 406 of 1999 (S-reg) and my windscreen wiper motor recently died.
I purchased a second-hand one on ebay and somehow managed to get the wrong type (mine has a 5 pins black flat connector whereas the one I received has a 4 pins Brown Square connector...).
Any idea if I could re-wire this wiper motor to suit my circuit???
Thanks in advance.
